Tor Browser will not run due to libevent was not found on Windows

Huh, okay. Where did you get Tor Browser from and where did you install it? If you look at your Tor Browser installation, which libevent*.dll do you have in your Browser\TorBrowser\Tor folder? Could you list the contents of that folder in this ticket? Does the issue happen as well with a clean, new bundle downloaded from our website and installed to a different location (in case you have not done so)?
